Applying Patch 42 (January 2011)

Release for Microsoft Windows (32-Bit)
You should administer one Oracle product, one Oracle home at a time, for its particular Bundle Patch Update. Each Oracle home will have its own requirements. We are updating Oracle Database as below.

OPatch Utility
You must use the OPatch utility release or later. If the Oracle inventory is not setup correctly, this utility will fail. To check accessibility to the inventory you can use the opatch lsinventory command. The utility must be in the PATH definition, or you must call it specifying its full path. For example:
%ORACLE_HOME%/OPatch/opatch lsinventory
D:\oracle\product\10.2.0\db_1\OPatch>set ORACLE_HOME=D:\oracle\product\10.2.0\db_1

D:\oracle\product\10.2.0\db_1\OPatch>opatch lsinventory

There are 2 products installed in this Oracle Home.

There are no Interim patches installed in this Oracle Home.
OPatch succeeded.

Back up the current database that is installed, the  %ORACLE_HOME% directory and Oracle inventory under c:\Program  files\oracle directory.

Patch Installation Instructions for Single Instance
Follow these steps:
Cleanly shut down all processes running from the ORACLE_HOME. Shutdown all databases , listeners etc. Check Oracle processes using windows task manager and kill them if required like hsodbc.exe.

Set the ORACLE_HOME environment variable to the correct Oracle home that needs to be patched.

Go to the directory where you downloaded the patch:
Ensure that the directory containing the OPatch script appears in your PATH setting. Enter the following command to run OPatch
D:\PatchesTobeApplied\p10349197_10204_Win32_Jan2011PatchBundle\10349197>opatch apply

Inspect the opatch.log file generated in %ORACLE_HOME%\cfgtoollogs\opatch for any errors.

Is the local system ready for patching? [y|n]

User Responded with: Y

Verifying the update...
Inventory check OK: Patch ID 10349197 is registered in Oracle Home inventory with proper meta-data.
Files check OK: Files from Patch ID 10349197 are present in Oracle Home.

Return Code = 0

The local system has been patched and can be restarted.

OPatch succeeded.

Post Installation Instructions
Start the OracleService and Oracle Listener Services.
Start all database instances running out of the ORACLE_HOME that you just patched and run the scripts as below.

If catcpu.sql reports any Invalid Objects, compile the invalid objects as follows.
(For large numbers of objects, this compilation step can take some time. If you are applying this patch through the Oracle Enterprise Manager console, you will be prompted to run this compilation script.)
cd %ORACLE_HOME%\rdbms\admin  
SQL> @utlprp.sql 0

To check for invalid objects, execute the following statement:

Recompiling Views in the Database
You must recompile views for all database.
If you want to check whether view recompilation has already been performed for the database, execute the following statement.
SELECT * FROM registry$history where ID = '6452863';
If the view recompilation has been performed, this statement returns one row. If the view recompilation has not been performed, this statement returns no rows.
To recompile the views for each database instance running out of the ORACLE_HOME being patched , follow these steps:
Run the pre-check script, which reports the maximum number of views and objects that may be recompiled:
cd %ORACLE_HOME%\BUNDLE\view_recompile
sqlplus /nolog
SQL> @recompile_precheck_jan2008cpu.sql
SQL> @recompile_precheck_jan2008cpu.sql

Running precheck.sql...

Number of views to be recompiled :2216

Number of objects to be recompiled :51540
Please follow the README.txt instructions for running viewrecomp.sql

PL/SQL procedure successfully completed.

The purpose of this step is to help you determine whether view recompilation should be done at the same time as the Bundle install, or scheduled later.

Run the view recompilation script. Note that this script is run with the database in upgrade mode, which restricts connections as SYSDBA.
